Abstract

Monoclonal antibodies (mAbs) were prepared against one UK isolate of turkey rhinotracheitis virus (TRTV). Those which were virus-neutralizing were selected and used, together with polyclonal antisera raised to each isolate in turkeys, in cross-neutralization tests against TRTV strains isolated in the UK and elsewhere. Whilst the polyclonal antisera showed that there was some diversity between them, all strains examined belonged to one serotype. The TRTV strains isolated in the UK could clearly be differentiated from those isolated elsewhere by some of the mAbs. Isolates of TRTV made in South Africa in 1978 and UK in 1985 were more closely related than were isolates made in UK and France within a few months. TRTV strains isolated from turkeys and chickens could not be differentiated. Some mAbs were found to be group-specific in that they neutralized all TRTV strains examined. All mAbs were of either the IgGl or IgG2a isotype and recognized the surface G glycoprotein.
